Look for increasing development of bioplastics for the medical market. In one of the more interesting announcements at last month’s MD&M show in Anaheim, CA, Arkema said it is in the process of developing a sustainable, bio-based acrylic polymer for medical devices that will feature extremely high impact strength. Introduction is scheduled for mid-2011.
No details are currently available, but it’s expected the compound will be an acrylic blended with polylactic acid (PLA), possibly in the 20 to 40 percent range. That route would be no surprise because Arkema is a major developer of additives that boost performance (particularly impact resistance) o of PLA, which is a thermoplastic aliphatic polyester derived from corn starch, sugar cane, and other crops, even tapioca.
Arkema scientists are looking for feedstocks that could produce acrylic in place of methyl methacrylate (MMA), which is in very short supply. Demand for MMA is rising, but supply is declining due to plant closings. Major chemical producers, such as Dow, are putting less emphasis on bulk petrochemicals. Climate change is also an issue in the biomonomer development, but not the key driver.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
The 100-percent solar-powered Solar Impulse plane flies on a piloted, cross-country flight this summer over the US as a prelude to the longer, round-the-world flight by its successor aircraft planned for 2015.
GE Aviation expects to chop off about 25 percent of the total 3D printing time of metallic production components for its LEAP Turbofan engine, using in-process inspection. That's pretty amazing, considering how slow additive manufacturing (AM) build times usually are.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
